Vibrant is super clean, light and was built with minimalism in mind. That said, the theme’s stand-out elements like the unique menu display, comment form and per-post/page custom header colors ensure it doesn’t look generic and is immediately memorable to the user.
Vibrant can also serve many purposes. Use it for a simple blog, a mobile home for your business, to show off your portfolio, etc. It can also be used as a secondary, mobile-only theme on your existing WordPress installation or set up as the main theme on a brand new installation. You can even use it for a full-blown desktop site if you so choose.
